I am from Laravel. In Laravel we have to develop admin panel separately. But I found there is a built in Admin panel in django.
Should I develop Admin Panel separately or should I use build in Admin Panel ?
It depends upon exactly what you want this “admin panel” to do for you, and how you’re going to use it.
I suggest you read the docs at The Django admin site | Django documentation | Django . The first two paragraphs describe when it should (or shouldn’t) be used and the rest of the page describes how to use it.
Additionally, if you work your way through the Official Django Tutorial, it’ll walk you through using it the first time.
